MAKING1 WIRE.

SPECIFICATION forming part of Letters Patent No. 293,011, dated February 5, 1884.

y l `application filed February 21, 1883. (No model.) l

and EDWIN J. WA'rsoN, both of Worcester, in the county of forcester and State of Massa! chusetts, have invented certain new and use ful Improvements in Apparatuses for Straighti en ing, Cleaning,

and Reducing or Shaping Wre or "Wire Rods; and We do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of thisspeciiication, and in which- Figures l and 2 represent a top or plan view and side view, respectively, of an apparatus for carrying out our aforesaid improvements, the same being shown in combination with the first set of rolls oi' .a continuous orother wire-rod-rolling mill. Figs. 3 and 4 represent modifications,which will be l1ereinafter more fully explained.

Our invention relates to improvements in apparatuses for `st13igliteni,ng, c leanin0 and red nemo' or sha nino' nnreoiinnrcrodscontinuons]ypnpysepinttenoperaiions, as hereinafteLmore-fullg described. Its objects are greater econoni ndrtlle production of a better quality'gfgrirgids than can now be obtained.A 'I

To enable those skilled in the art to `which our invention belongs to make and use the same, We will proceed to describe it more in detail.

In the drawings, A A represent a set of reducing or shaping rolls, which are fitted to turn in suitable bearings, B B, in housings C C. As said housings C C and parts connected therewith `are of ordinary and \vell-kno\vn construction, no further description in reference to the same is here necessary.

The parts marked I) represent straightenin g or guide rolls, for guiding and removing the kinks or bends in the wire a, preparatory to being cleaned or otherwise treated.

`The parts E are nozzles or pipes forcenductinga sand-blast (from any suitable device for producing said blast) againstv the surface ofthe wire or Wire rods, to remove the scales or dirtfroin the surface of the same as it is continuously fed forward.

i i F F are brush-Wheels, made of fine Wire or similar material, for removing any scales or dirt that may have escaped the sand-blast, and G G are pipes for conducting water lagainst the surface of the Wire or Wire rods after the cleaning operations, to rinse off such loose dirt as may remain upon it after said operations. As the Water is poured onto the Wire, it passes into a reservoir or tank, H, which is provided with an outlet and Waste pipe, b, for conducting the Waste Water Where desired. In this instance the brush-WheelsF are iitted to turn in bearings 'formed in the upright standards c c, formed upon or secured to the side of the tank II; but any other means of support may be employed for the saine, if preferred. Said wheels, as Well as their straightening or guide rolls D, may be turned by any suitable and convenient driving mechanism.

If desired, the water poured upon the Wire a may be mixed with lime, soda, or similar chemicals for preventing said Wire from corroding; and, it' preferred, instead of ponr ing the aforesaid mixture upon the Wire by means of pipes G, said pipes 4may be dispensed l with, and the Wire thus treated bypassing it. und er guide-rolls or their equivalents through a bath of said mixture.

The sand-blast may be applied through any v desired number of tubes or nozzles IE, and any desired number of brush-Wheels maybe employed for the purpose before described. The arrangement oi' both may also be varied for producing the aforesaid results, and the Wire may be conducted over suitable guides as it is fed forward, so that it Will pass through and receive the action of thc sand-blast any desircd number of times.

Our invention may be applied not only toV is also applicable in treating any size, shape, f

or kind of Wire requiring such treatment.'

In Fig. 3 We have represented only the straightening orguide rolls D, nozzles or pipes E, and a portion of the housings Gand rolls A, the brush-wheels F, Water-pipes G, and tank II being removed. rIhis arrangement of `at one operation,

the apparatus may b e employed with good effect for certain kinds of wire-as, for instance, wire whose surface may be easily cleaned, orl which requires less cleaning than other kinds of wire. In Fig. 4 the same arrangement is shown after straightening in connection with a reducing-die, I.' The same or similar result to that above described might be obtained by using one or more sets of brush-wheels F in place of the sand-blast between the straightening and guide rolls and rolls A or die l.

Wires or wire rods maybe treated continuously by ourimproved apparatus; or they may be straightened, cleaned, and reduced or molded into different shapes by separate operations 5 or they may be straightened and cleaned and afterward reduced, shaped, or drawn at another operation.-

That theI advantages of our invention may be more readilyunderstood,we will state what some of the principal disadvantages of old apparatuses are. In the iirst place, alarge amount of room for the cleaning-vats and dry-houses is required, and therefore requiring a large and expensive outlay for buildings and appliances. A great deal of time is unnecessarily wasted in loosening up the coils preparatory to immersing them in the acid cleaning-bath, so that the acid can penetrate between the strands and clean all parts as perfectly as possible. This is more especially true in regard to flat wire or rods, which require a great deal more time for this purpose than round wire. This, together with the number of times the wire 'must be handled, makes it an expensive operation. By the use of our apparatus the wire rods can be taken as they leave the rolling-inill, or wire' as it leaves the annealing-furnaces, and cleaned, as before described, without any previous preparation, and at the same operation reduced or shaped in size, thus wire is acted upon, being treated singly instead of in a coil, where one strand is liable to come in contact and be covered by another. Another objection to the old apparatuses is that by the use of acids the quality of the wire is greatly i1npaired,which, as is seen, is entirely obviated by our invention.

Ve are aware it is not new to clean the sur.- i'ace of metals by means of a Sandblast, and' therefore make no claim, broadly, to such fea-A ture, our invention being conned to its coinbination with a rolling-mill for manufacturing wire or wire rods by a continuous operation, as hereinbefore described.

We are also aware it is not new to clean the surfaces of saw-blades and similar sheets of metal by means of a sand-blast, and therefore make no claim, broadly, to the same, our claim being confined simply to its use in connection with vapparatuses for straightening, cleaning, and reducing or shaping wire or wire rods, as hereinbefore set forth.

Having described our improvements in apparatuses for straightening, cleaning, and reducing or shaping wire or wire rods, what we claim therein as new and of our invention, and desire to secure by Letters Patent, is-

1. The combination of means whereby the sand-blast isapplied through one or more nozzles, E,witl1 the straighteningrolls D and reducing-rolls A, substantially as and for the purpose set forth.

2. The combination of means whereby the sand-blast is applied through one or more nozzles, E, with the straightening-rolls l), substantially as and for the purpose set forth.

3. The combination of means whereby the sand-blast is applied through one or more noz- Vzles, E, with the reducing-rolls A, substantially as and for` the purpose set forth.
